Carbon Nanotube Diameter Dependence of the Schottky Barrier Height for Pd – Carbon Nanotube Contacts
Artikel i vetenskaplig tidskrift, 2009
Direct measurements are presented of the Schottky barrier (SB) heights of carbon nanotube
devices contacted with Pd electrodes. The SB barrier heights were determined from the
activation energy of the temperature-dependent thermionic emission current in the off-state of
the devices. The barrier heights generally decrease with increasing diameter of the nanotubes
and they are in agreement with the values expected when assuming little or no influence of
Fermi level pinning.
